David Hockney's iPhone Art.

I discovered this after I had purchased my iPhone when artist Susan Adsett told me about it on Twitter. I've never known a lot about Hockney's work but this stuff really caught my eye, partly because it's using a tool I really like but also because the work is so beautiful and has a great feel to it. You can even print one off and have an original. Very interesting interview with Mr.Hockney on the subject can be found here.
